yes I had this exact problem, which is caused when the serial port
is hung up by getty, it drops the DTR (which, since its a null modem),
drops carrier) and gived getty a HUP causing it to quit.
I got around this my slightly modifying serial.c so that it didnt ever
hang up a serial port. (no hardware of mine needs it)
You don't need to modify the kernel. All you need to do is configure
your getty program to set the CLOCAL flag. Then the serial driver will
ignore DTR.
